How do you get response code when using Custom Object instead of Httpresponse

Question

When I use

val pipeline: HttpRequest => Future[HttpResponse] = addHeader(.......) ~> sendReceive ~>       unmarshal[HttpResponse]        

then I can get the Status code as it an object of HttpResponse using

val futureResponse = pipeline(Post(url, body)) futureResponse.map(_.status)

However, when I use a custom unmarshaller as:

val pipeline: HttpRequest => Future[MyResponse] = addHeader(.......) ~> sendReceive ~>      unmarshal[MyResponse]

using

val myfutureResponse = pipeline(Post(url, body))
myutureResponse.map(_.status)

doesn't compile as it cannot find status. How do I get the status code here? I need to use a custom unmarshaller to be able to deserialize my json result.

Answer 1

Finally I found an answer based on your suggestion

private def unmarshal[T: Unmarshaller](response: HttpResponse): T = {
response.entity.as[T] match {
  case Right(value) => value
  case Left(error)  ⇒ throw new PipelineException(error.toString)
}

}

I changed my pipeline method to be

val pipeline: HttpRequest => HttpResponse = addHeader(.......) ~> sendReceive
val searchResponse = pipeline(Post(urlwithpath, queryString)).map {
  response => response.status match {
    case StatusCodes.OK =>
      Some(unmarshal[MyResponse](response))
    case StatusCodes.NotFound => print(StatusCodes.NotFound)
   }
}

Now that I have got this out of the way, I will learn the API properly
